Remarks. — Professor Duderleiu places Diaseris fragilis Alcock in the .s3'nonymy 

 of Fungia jpatMn, and he may be correct. The two .specinieti.s from the Hawaiian 

 Islands, however, are so diti'erent from the .•ipecimons of F. jMtdIa that I prefer to 

 keep them apart, at least for the present. The only difference that I can discover 

 between the Hawaiian specimens and Doctor Alcock's from the Indian Ocean is the 

 thicker septa of one of the fornicr specimens.

Description of a specimen without tentacular lobes, from, Lnysan. — Corallum 

 oval, margins rounded, upper surface very slightly arched, almost flat, base practi- 

 cally flat, somewhat irregular. Length, 81. .5 mm.; width, .">(!; height, 18.5 nnu. 

 Lobation of the edge very slight. 



Underside costate, the costse equal or sube(iual in size, with iiregularlj' dentate 

 margins, teeth sometimes forked, granulations on both the teeth and the sides of the 

 costw. ^Middle of the base damaged. Plural perforations very scarce. 



Septa equal at the periphery of the corallunL A little over forty bound the 

 fossa with their inner margins; about the same number are only slightly shorter; 

 the septa next in size extend half, or luore, of the distance to the a.\is from the 

 periphery, drop down suddenly, and are contiiuied adorally by a thinner, lower 

 portion. In a system there are one or two still shorter sets of septa. Their courses 

 are somewhat undulate. The septa are rather thin. Septal margins finely dentate, 

 or subentire. Tentacular lobes weakly developed or absent. Septal faces rather closely 

 and finely granulate. Just below the margin rather fre(|iiently fher(> are knife-edge 

 ridges running perpendicular to the margin and corresponding in position to septal 

 dentations. 



Localitij. — Laysan Island, 1 .specimen. 



BemarkK. — This specimen is F. sciitaria typica, according to Doderleiu's 

 description." 



He .says: 



The typical Fmigia .inilnrid Lamarck possesses only an indistinct or weak tentacular lobe, which 

 can be recognized only through the thirkeniiig of the corresponding places on the septa; the under- 

 side is u.fually thickly spinulose, the disk is flat or arched. 



As arule the sejit^i of the specimen justdescribe<l are somewhat thickened, but not greatly; in the 

 places corresponding to the tentacular lolx-s, however, distinct lol>es are commonly absent. 



The Bureau of Fisheries steamer Albatross foi'tunafely obtained some young 

 F(ingi;e, probabl}^ F. scidariit, although it can not be positively (h'cided that they are 

 not F. pamnotensis Stutchbury. One specimen is represented by three views on Plate 

 XXVIII, figs. 3, 3a, 35. It is an anthocormus, consisting of three anthoblasts, one of
